63105: Channel does not support this action

This error occurs when your API request asks a messaging channel to perform an action that the selected channel does not support. Review the channel you are using, the feature you requested, and any content or Message resource parameters included in the request.

• You tried to use a feature that is available only on specific channels. For example, scheduled messaging is supported for SMS, MMS, RCS, and WhatsApp.
• You submitted content or media that the selected channel does not support.
• You used a product and channel combination that is not supported. For example, Conversations and Flex do not support RCS.

• Send the request through a channel that supports the action you need.
• If you are sending rich content, choose a content type and media type that the destination channel supports.
• If you are scheduling a message, use a supported channel and include the required MessagingServiceSid, ScheduleType, and SendAt parameters.
• If the selected channel does not support the requested feature, remove the unsupported action from the request or redesign the flow for a supported channel.
